JOHN BRUCE TATE, OF ALTOONA, PENNSYLVANIA.

LOCOMOTIVE.

SPECIFICATION forming part of Letters Patent No. 643,560, dated February 13, 1900. Application filed August 8,1899. Serial No. 726,565. (No model.)

To (ZZZ whom, it may concern:

Be it known that 1, JOHN BRUCE TATE, a resident of Altoona, in the county of Blair and State of Pennsylvania, have invented certain new and useful Improvements in Locomotives; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in locomotives, and more particularly to means for securing the boiler on the frame of a locomotive, the object of the invention being to provide means of the above-mentioned character which will securely hold a boiler in place and at the same time permit the ready removal of the boiler when desired.

A further object is to simplify and improve boiler mountings.

With these objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a view illustrating my improvements. Fig. 2 is a view in transverse section through the .boiler and frame, and Figs. 3 and 4 are views of details.

A represents an engine-boiler,and B a frame on which it is mounted. The boiler A is made 7 with a mud-ring 1, provided at opposite points with depending blocks or extensions 2, provided on their outer faces with longitudinal grooves 3, for a purpose which will now be explained. I preferably provide two of these blocks on each side of the boiler and dispose them a sufficient distance apart for the accommodation of the yoke 4 for the axle-box of the frame, and a metal strip 5 is placed between the blocks 2 and upper face of the frame B to take up wear. My improved clampingplate 6, made L-shaped in cross-section and provided on its upper edge with an inwardlyprojecting flange or lip 7 to enter the groove 3 in the block 2, is placed against the frame and block 2, and a plate or strip 8 is disposed against the inner face of the block 2 and frame B, and said plate 8 and clamping-plate 6 are made with alined holes for the reception of bolts 10 to secure them in place. The bolts 10 are preferably made screw-threaded at each end and provided with an enlargement 11 between their ends to fit into a socket 12 in the frame, and the screw-threaded ends of the bolts extend through the plates 6 and 8 for the reception of nuts 13 for securing the parts together. It will thus be seen that by my improved means of securing the boiler to its frame I dispense entirely with the necessity of securing a pad to the boiler-plate, which requires a vast number of bolts and of necessity requires a great amount of trouble to separate the boiler and frame should it be found desirable to do so. It will also be seen that by fastening the boiler to the frame by my improved means I dispense entirely with the necessity of fastening anything to the boiler-plate, which of necessity would, as is the case with the devices now in use, cause corrosion of the metal, which would shorten the life of the boiler and at the same time be a constant source of danger to the fire-box and Patent, is

1. In a boiler-mounting, the combination with the mud-ring of the boiler and a frame, of a block depending from said mud-ring and a clamp secured to said frame and detachably connected with said depending block.

2. In a device for securing a locomotiveboiler on its frame, the combination with a mud-ring, of a block secured to the mud-ring having a groove therein, a clamp secured to the frame and a flange or lip on the clamp to enter the groove and secure the block and frame together.

3. In a device for securing a locomotiveboiler on its frame, the combination with a mud-ring, of blocks secured to the mud-ring and having grooves therein, clamping-plates disposed on the outer faces of the frame, flanges or lips on said plates to enter the grooves in the blocks, strips or plates disposed on the inner faces of the frame, bolts securing said first and last mentioned plates together and to the frame and a strip disposed between said blocks and frame.

4. In a device for securing a locomotive boiler on the frame, the combination with a mud-ring, of a block integral with the mudring and having a groove therein, a clampingplatehavingalip to enter said groove, another plate disposed on the opposite face of the JOHN BRUCE TATE.
